Bugfixes, more debug info and tested with the latest IDE and ESP Arduino releses
Another small round-up release, the MCU temperature is reported and a nasty corrupt-SPIFFS related lock-up is catered for (backports from the master branch).
Compiling for the 2.x ESP Arduino core is fixed, and compiling/uploading and use have been re-tested using the latest Arduino IDE (1.8.15) and ESP Core (2.0.0).
